They Bulk Upload Their NFT Collection

Their words, not ours. Learn how was their experience using our Opensea Bulk Upload tool.

"Our team had the early opportunity to use the NFT Bulk Upload Tool to test our project. After a successful set of transactions there we gave it shot on the Polygon main-net. Once the contract was complete, we began uploading our 10,000 NFT collection in batches. We got our project uploaded to OpenSea precisely as specified and we could not have done it so effortlessly without the NFT Bulk Upload Tool."

"After more than a year of searching for a 'simple and efficient' system to upload our first collection to OpenSea, we finally discovered NFT Bulk. Simple, fast and efficient!"

"I uploaded a 10,000 item collection to Opensea using NFT Bulk, and having been through the process I can say that it is the perfect place to bulk upload NFTs. They have a great chat box feature where agents reply in a timely fashion, a very affordable price for Polygon contract creation, and they've even introduced a Chrome extension for the price listing process. I really needed NFT Bulk because of the nature of my collection. Their service is 10/10 and I recommend it to you."
